Graffiti crew MOSES & TAPS™ that is also known as ERNI & BERT™ or INTERNATIONAL TOPSPRAYER: MOSES & TAPS™, has grabbed the attention of both law enforcement officials and art critics. The ever-changing name of this collective is not borne out of indecision or marketing. It rather helps conceal the identities of its members. In 2011, the collective, who rigorously decided against an online presence, published a volume of their works for the first time. Whether graffiti is described as scribbling, art, vandalism, or urban propaganda, it has long hovered between unlawful and lawful expression. Today, the gap between the two has narrowed. While street graffiti remains a form of vandalism, it is increasingly considered an art form, too. Some of those notorious paint sprayers are now defined as graffiti artists, whose works are exhibited, traded, collected, and analyzed. Graffiti has become a key influence in the world of contemporary art.
